and it makes a weird ticking noise around tha turbo area...
at first I thought I blew my turbo, being that tha guage and reading boost...
but my turbo iz fine, I went and had it checked...
no1 seems to know whats wrong with my car...

Tho i did find a couple of missing hoses...
and I think thats tha problem...
but being that there missing...
I don't know where they start and where they finish...
and theres no other TGP's that i know of around my town that a could look at...
to see there motor and find out where thoze hoses go...

Here's Jeff M.'s engine compartment. It looks pretty much stock to me. Maybe he'll cut in and prove me wrong, but it will lead you in the right direction.....


When all else fails, punch it.

There is not a hose there. It vents to the atmosphere.

Thanx, I found my problem...
I need a crossover pipe...

If you're talking about the 90 degree elbow, it goes to the turbocharger wastegate actuator.  The one behind it is open for venting.
